Notes

  • Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat at 350°F for 5–7 minutes. Freeze cooled squares in a freezer-safe bag for up to 3 months; thaw in the fridge overnight before reheating.
  • Variations: Swap Monterey Jack for cheddar or pepper jack for a spicy kick. Add diced bell peppers or mushrooms for extra veggies. Use a 1:1 gluten-free flour blend for a gluten-free version.
  • Serving Ideas: Serve on a party platter with marinara or ranch dip, as a brunch side with scrambled eggs, or as a lunchbox snack.
  • Tips: Use freshly shredded cheese to avoid anti-caking agents. Squeeze spinach thoroughly to prevent a watery texture.
  • Beverage Pairings: Pair with Sauvignon Blanc, light lager, or sparkling water with lemon for a refreshing complement.
